Description

The invention relates to a carriage for a transport vehicle for transporting roll containers and a safety device for container rolls for use in transport vehicles for transporting roll containers. The invention also relates to a safety device for container rolls on a transport vehicle for transporting roll containers and to a transport vehicle with a safety device for container rolls.

Roll containers are containers with rollers and are widely used for collecting and transporting bulk and piece goods. The roll containers include, for. B. standardized roll-off container with a cuboid container, a mounting bracket for the charger on the front, rear doors and a sub-frame with a pair of rollers that makes the roll container rollable. In addition, there are many special designs that use the roll-off container system or use it modified, which are equipped with different structures and sometimes with pairs of rollers and / or mounting brackets on both sides. A roll container of the type in question here is a container or a special structure that uses rollers for the loading or relocation processes and has at least one receiving part, e.g. a bracket, on which a charger can attack.

Special chargers lift and pull the roll containers from the floor onto the transport vehicle or push the containers back onto the designated storage area. With Vehicles equipped with the charger can also be used to load and unload other transport vehicles with a roll container by pushing the container from their own onto another vehicle and unloading it in the opposite way.

In order to move the container from the container placement position on the rear or front side of the transport vehicle to the container transport position, the transport vehicle to be loaded either has roller tracks on which the roll container can roll with its rollers, or it is equipped with a carriage that places the one on it Roll container moved in the longitudinal direction of the vehicle into the transport position. The slide variants are advantageous because of their lower net weight and the higher transport masses that this makes possible.

A transport vehicle for roll containers of the type in question here is a vehicle for transporting roll containers without its own charger, which is equipped with a slide system. The transport vehicle can be both a truck and a trailer vehicle. Such a transport vehicle is usually equipped with exactly one carriage in order to receive and transport a roll container with it. In the case of short roll containers or in countries whose permissible transport lengths allow the transport of two roll containers, trailer vehicles with two sleds are also possible.

When loading and unloading the transport vehicle, the carriage is in a container placement position, that is, at a short distance from the approaching vehicle with the charger and the container, for example at the rear of the vehicle. In the case of special trailers such as tipping trailers or special handling technologies, the container can also be translated from the front - i.e. from the drawbar side of the trailer vehicle.

From the container placement position, the roll container is moved into the container transport position by the thrust of the loading device on the carriage. In this case, the roll container is carried by the carriage in the area where its container rolls are located, and the vehicle longitudinal members usually form the rail track on which the carriage slides or rolls.

In order to be able to roll, the rollers protrude under the contact surface of the container substructure. The carriage of the transport vehicle therefore has depressions as roller receptacles for receiving the rollers.

The transfer conditions rarely allow the charger to place the container directly and immediately on the slide. As a rule, the roll container is maneuvered onto the carriage via guide devices with a guide function and rolled with the rollers into the roller mounts, the way into and out of the depressions is often made possible or facilitated by inclined ramps on the depressions. The path on which a container roll is guided into a corresponding roll receptacle is referred to below as the roll feed contour and can be formed by parts of the carriage, the chassis or both.

In the context of this description, the directions and position assignments for the carriage and its components are defined as follows: the side facing the container transport position of the carriage is "front", the side facing the container placement position is "rear". Regardless of the loading direction on the trailer, a roll container is guided in accordance with this definition during loading with its rollers over the rear part of the slide into the roll mounts, the slide moves forward in the direction of its container transport position during loading.

The transport processes require effective load securing, in this case the roll container. Common measures are claw locks that clamp the container on its lower frame on the vehicle and, for example, in DE 44 12 085 are shown, furthermore stops and centering.

It is also necessary to secure a roll container on the slide, which is to prevent the roll container with its rollers from rolling out or jumping out of the roll holder of the slide. During road transport, this safety device must, among other things, absorb the deceleration forces when braking in the direction of travel and also when reversing.

A front limitation of the recess of the roller mount can be increased so that it acts as a stop. In this way, a container roll can be secured in the recess of the roll holder in the loading direction, which corresponds to the direction of travel during transport for a transport vehicle loaded from the rear.

This possibility only exists to a limited extent in the opposite direction at the rear boundary of the roller mount, as this area must be capable of being driven over and is typically designed as an inclined ramp, which can lead to hazards or damage in certain driving situations.

But even when the container is being unloaded from the vehicle, it can happen that the container with its rollers is pulled out of the roller mounts via the ramp due to lack of support before the carriage has reached its intended end position. In addition, during a subsequent empty run, the slide cannot be secured in position by the measures provided in the container placement position, so that the slide can move in an uncontrolled manner during the empty journey and must be manually withdrawn into the container placement position before the container is moved again.

document DE 20 2005 002137 U1 discloses a slide according to the preamble of claim 1 and a safety device according to the preamble of claim 5. Z

The aim of the invention is to create an improved securing of container rolls on a slide, which eliminates the disadvantages named for the prior art, in particular prevents container rolls from being able to move unintentionally out of corresponding depressions of roll receptacles of a slide.

The above object is achieved according to the invention by a safety device and a slide with a safety device for container rolls on a transport vehicle for transporting roll containers with the features according to claim 1.

Correspondingly, a carriage for a transport vehicle for transporting roll containers is proposed, which has depressions as roll receptacles for receiving container rolls of a roll container to be transported. The depressions and thus the roller receptacles each have a ramp which is designed in such a way that a respective container roller can move into or out of the depression along the ramp. According to the invention, a safety device with a locking element is arranged in the area of the ramp, which between a locking position, in which the locking element blocks an extension of a roller along the ramp from the recess, and a release position, in which the locking element from an extension of a roller along the ramp allows the recess to move back and forth. The safety device has a displacement device which is designed to move the locking element into its locking position and / or into its release position, the displacement device moving the locking element out of its release position into its locking position or vice versa in conjunction with the force of gravity of one connected to the locking element Mass, caused by a spring force of a spring mechanically connected to the locking element and / or by means of a control member mechanically connected to the locking element, which is arranged so that it is actuated in the application by a control element attached to the transport vehicle when the carriage is relative to the Transport vehicle moves. The displacement device is thus designed in such a way that it moves the locking element, for example, both in its locking position and in its release position forcibly or that the displacement device, the locking element against a restoring counterforce, z. B. a spring force or the force of gravity, moved into its locked position or its release position.

The starting point is a transport vehicle for transporting roll containers, equipped with a slide on which the roll container can be placed and is moved from the container placement position to the container transport position during loading and back to the container placement position for unloading. The carriage has recesses that serve as roll mounts for the container rolls. The container rolls get into the roll receptacles along a roll guide contour the z. B. includes an inclined ramp. While the front limits of the roll receptacles are raised and can serve as a front stop, the rear limits - namely the ramps - of the roll receptacles for placing or removing the roll container must be able to be driven over, so that there is less securing effect for the container rolls in this direction.

According to a variant of the invention, provision is made to secure a container roll in the roll holder of the slide in the direction of a rear boundary of the roll holder in that a locking element in the area of the roll holder of the slide can be pivoted between a blocking position in an upper pivot position and a release position in a lower pivot position is arranged. In the upper pivot position, the locking element projects beyond the ramp behind the container roll located in the roll holder and partially or completely covers the container roll. In its lower pivot position, the locking element is lowered under the ramp and can therefore be rolled over by the container roll. In order to move the locking element into the desired upper or lower pivoting position and to hold it there, for example one's own gravity, a configured displacement device, an obstacle body acting in connection with the slide movement on the locking element as a control element or combinations of these measures can be used. One or more stops limit the movement of the locking element in the pivoting positions.

In the preferred embodiment of the invention, a pivot bearing of the pivotable locking element is arranged below the ramp or the container roll located in the roll holder, so that all components in the lower pivot position are below the contour to be rolled over and are arranged to save space within the roll width are. Alternatively, however, with greater effort, a storage of the locking element outside the container roll width z. B. possible by two aligned pivot points outside the role.

According to one embodiment it is provided that the rotatably mounted locking element is guided into the desired pivoting position, in particular the locking position, by its own gravity. This happens, for example, that the locking element, having a stabilizing effect, has a greater mass below the pivot point than above the pivot bearing, whereby the locking element is pivoted into the upper position. Alternatively or as an additional support, a displacement device can be provided. According to the invention, these can be steel, air or rubber springs, which can act instead of or in addition to gravity. Furthermore, pneumatically, hydraulically or electrically driven actuations such. B. working cylinder realizable. They are particularly suitable for moving the locking element directly or indirectly in the areas of the container transport position or the starting position, mounted on the chassis, whereby with this fastening the energy supply of the displacement devices does not have to follow the movement of the slide.

A further special form of the displacement device can be a mechanical release system. In this case, the locking element strikes a release element during the slide movement and is moved by this into one of the pivoting positions.

The blocking element is preferably 2 cm thick or thicker. This means that the blocking element is made, for example, from a steel sheet with a thickness of 2 cm or more.

According to a further preferred embodiment variant, the blocking element can be composed of two or more elements arranged parallel to one another.

In the variant embodiment of the invention, according to which an obstacle body is provided, the obstacle body preferably has a slope and is arranged below the slide in the area of the container placement position so that the lower contour of the locking element moves into the container placement position when the slide moves moves on the ascending path in the direction of movement and thereby rotates from the upper to the lower pivot position.

The obstacle body is preferably arranged in the area of the sled transport position or, starting in front of it, below the rail track for the sled so that the locking element hits the obstacle body with its lower region or on the obstacle directly or by means of coupling elements when the sled is moved into the container transport position - moves along the body and rotates from the lower to the upper pivot position.

The slide or the safety device preferably has a control member which is pivotably connected to the locking element and is guided pivotably and longitudinally displaceably in a longitudinal guide on the slide, a free end of the control member protruding downward beyond the lower contour of the recess of the slide. The free end of the control member can thus interact with a moving slide with a stationary control element on the transport vehicle, with which it comes into abutment in the course of a slide movement and is displaced in the course of the further slide movement in such a way that it moves the blocking element from its release position into the blocking position or vice versa moves. Accordingly, a fixed control element is preferably provided in a suitable position on the transport vehicle.

According to the invention, the object is also achieved by a transport vehicle in which an obstacle body or a control element, for. B. in the form of a stop is provided for deflecting the locking element. The obstacle body is arranged on the vehicle frame where the slide is located when the locking element is to be deflected.

Preferably, the locking element for the movement on the obstacle body has at least one rounding in the lower area or is provided with a roller.

In all design variants, the locking element can be used to secure one side only for one container roll or in pairs for both rollers on the slide.

The securing device preferably has at least one sensor in order to detect at least one swivel position, preferably the securing upper swivel position of the locking element.

Figure 1 shows a transport vehicle 10 in the form of a trailer for transporting roll containers, in particular roll-off containers. The transport vehicle 10 has a vehicle frame 11. A roll-off container 12 is shown schematically.

The roll-off container 12 has a cuboid container 14 which is mounted on a subframe 16 and has a pair of rollers 18 at one longitudinal end. At the opposite longitudinal end, the roll-off container has a mounting bracket. When the container is lifted on the mounting bracket, for example with the aid of a charger, the roll-off container 12 can roll on its pair of rollers 18.

This in Figure 1 The illustrated transport vehicle 10 has a carriage 22 which moves on a rail track 24 from a container placement position 26 to a container transport position 28 is to move. The rollers of the roller pair 18 are located in corresponding recesses 30 of the carriage 22.

Figure 1 shows on the left the carriage 22 in the container transport position. On the right side of the Figure 1 the same carriage 22 is shown in the container placement position 26. As in Figure 1 is indicated, the container 14 is raised when it is placed on its end, not shown, and can then be moved on the carriage 22 from the container attachment position 26 to the container transport position 28. When the carriage 22 is in the container transport position 28, the roll container 12 rests with its lower frame 16 on the transport vehicle 10.

Figure 2a shows the transport vehicle 10 without the container placed on it with the carriage 22 in the container placing position 26.

Figure 2b is an enlarged section from Figure 2a and shows details of a first embodiment of the carriage 22 with a safety device which has a blocking element 50.

The carriage 22 has a recess 30 as a roller receptacle for receiving a container roller 38. It should be noted that the in the Figures 2a and 2b The container roll 38 shown is not part of the carriage 22, but part of an otherwise not further shown roll container. The recess 30 has a ramp 40 at one end which allows a container roller such as the container roller 38 to move into the recess 30 or to move out of the recess 30.

In the exemplary embodiment shown, the ramp 40 is designed in such a way that it extends as far as a floor 36 of the respective roller mount 30. In alternative, not shown design variants, the ramp can also end at a distance from the bottom 36 of the roller receptacle 30 or also have different gradients.

The locking element 50 is pivotably mounted on a pivot bearing 52 which is fastened to an underside of the ramp 40. As a result, the locking element 50 can consist of an in Figure 2b Release position shown in a in Figure 2c Swivel shown locked position. The ramp 40 is provided with a slot through which the blocking element 50 can pivot, so that a blocking end 50.1 of the blocking element 50 in the blocking position of the blocking element 50 extends beyond the ramp 40 (see FIG Figure 2c ) while an end 50.2 of the locking element 50 facing away from the locking end 50.1 extends below the ramp 40 is located. The locking element 50 is designed so that the locking end 50.1 is lighter than the opposite end 50.2 so that the center of gravity of the locking element 50 is next to the pivot axis defined by the pivot bearing 52 that the locking element 50 is moved out of its release position solely by the force of weight the locked position swivels.

In alternative design variants (see for example Figures 5a and 5b ) the pivoting of the locking element from the release position into the locking position is supported by spring force.

In yet another variant, the locking element is provided with a more complex displacement device which comprises a control element mechanically connected to the locking element, which interacts with a control element fixedly connected to the transport vehicle when the slide is moved along the rail track 24 from the container placement position to the container transport position or vice versa.

Figures 3a to 3d and 4a to 4c show a corresponding embodiment. Also in the embodiment in Figures 3a to 3d and 4a to 4c the locking element 50 'is attached to the slide 22' so as to be pivotable about a pivot bearing 52 '. In the embodiment according to Figures 3a to 3d and 4a to 4c however, the locking element 50 ′ is pivotably connected to a control member 54. The control member 54 is guided in a longitudinal guide 56 on the slide 22 so as to be pivotable and longitudinally displaceable. A free end 58 of the control member 54 protrudes downward beyond the lower contour of the recess 30 of the slide 22. When the carriage 22 moves - for example with respect to the illustration in FIG Figures 3a and 3d or 4a and 4c to the left - the free end 58 of the control member 54 can come into abutment with a fixed control element (not shown) on the transport vehicle and in the course of a further slide movement with respect to the slide from the into the Figures 3a to 3d position shown in the Figures 4a to 4c position shown are pushed. This displacement of the control member 54 along the longitudinal guide 56 has the effect that both the control member 54 and the locking element 50 'pivot in such a way that the locking element 50' as a result moves out of its release position, which is shown in FIG Figures 3a to 3d is shown, is pivoted into its locking position, which is shown in Figures 4a to 4c.

Figure 5a shows another variant of a slide 22 with a safety device which has a locking element and a displacement device. In the in Figures 5a and 5b The illustrated embodiments, the locking element 50 ″ is designed similarly to the locking element 50 from the Figures 2a to 2c . The relocation facility consists of the in Figures 5a and 5b However, the illustrated embodiments not only simply in a massed, remote end of the locking element 50. Rather, the displacement device comprises a tension spring 60 and a roller 62. The tension spring 60 is so tensioned between the locking element 50 "and the carriage 22 that it the locking element 50" in its in Figure 5b Locked position shown pulls.

To the locking element 50 "from its in Figure 5b locked position shown in Figure 5a To move the release position shown, a control element 64 with a bevel 66 is provided in the rear area of the transport vehicle 10, which lifts the roller 62 on the locking element 50 ″ when the roller 62 hits the control element 64 due to a carriage movement - in the illustrated embodiment to the right and rolls on the slope 66 provided by the control element 64. The lifting of the roller 62 brought about by the control element 64 results in the locking element 50 ″ being moved from the locking position into the release position against the force of the spring 60. The in Figures 5a and 5b In the illustrated embodiment, the displacement device is thus formed by the spring 60 and the roller 62.
